GTA: Road of Fury

Living a post-apocalyptic world is such a drag because everyone is for themselves. This world ain't for the sweet and those easily faint. They would not last in such world. As such, you need to arm yourself if you want to travel because there are gangs on the road that will simply kill you just for fun.
In this game, your car is armed and dangerous because you would need to defend yourself against attacks. Each enemy you kill means money for you. You can use the money to upgrade your existing vehicle or simply buy a new one.
